IIVIPROV EMENTJN SHEET-METAL CANS.

The Schedule referred to in thesellettem Patent and making part of thesame.

To all whom it may concern Be it known that I, CONRAD SEIMEL, ofBrooklyn,

i the county of Kings, and State of New York, have Thisjnvention,reiates to an improved method of fastening the tops and bottoms tosheet-metal cans;

and

It consists in the peculiar construction of the joint for this purpose,so as to form a rigid, firm, and tight connection, at slight expense,and with but little labor.

In the drawings- A A represent the sides of a square sheetmetal can, .ofwhich B represents the ends or top and bottom.

In forming the joints, where the ends are united to the sides, thelatter are first struck or bent up with a flange, a, at right angles tothe main body B.

The top is then formed, as shown in fig. 1, with a right-angularflange,'1), upon the outside of the depression or gutter c.

The ends are applied to the sides by fitting the portion d of the.former over the flange a of the latter. They are then pressed or swagedtogether by dies, or other suitable means, which will impart to them acurved form without angles, as shown in fig. 2, the part d of the topand bottom fitting snugly against the curved under side of the flange a.

If desired, a wire, 0, maybe introduced between the flanges a d, asshown in fig. 3, before these parts are swaged up. in order to impartadditional strength to the joint.

\Vith a joint of this construction, solder is not absolutely necessaryto render it perfectly tight, as the parts are firmly pressed in contactover a comparatively large surface.

. If preferred, howeveri solder may be employed in' small quantities.

1t will be observed that these joints extend at right angles to thesides B and that they are therefore flatstened to form a widebearing-surface, upon which-the? cans rest. This is of great advantagein packing oilcans, as they are thereby enabled to sustain considerableweight without bending the flange, and conse quently loosening thejoint.

I am aware that sheet-m etal cans have heretofore been constructed withdiagnnal flanges, over which the edges of the tops and bottoms areformed, but this method I of construction does not 'form a safe jointfor packing cans of large capac1ty,jfrom the fact that the weight of thecans and their contents, which in transportation are generally subjectedto rough handling, tends tobend; .lihe j int outward. orintna-horizontalposit onand.

thereby loosen it,-causing leakage, and aconse'qucnt waste of material.

In this construction of cans, the principal means employed for holdingthejoints, is a thincoating of solder, which a slight blow frequentlybreaks, opening a wide seam, and rendering the can worthless. My improvement is designed to obviate this difficulty, because, as before stated,the joint forms a wide bcaring surface.

A blow upon this joint cannot have a tendency to 'open it, from the factthat the slight curve given the parts a b, directs the joint toward thebody of the can, thereby tightening instead of opening it,

When the strengthening-wire is used, the joint is rendered immovableunder the roughest handling to which this class of goods is generallysubjected.

The simplicity of my improved can, and theecon omy of its construction,render it a valuable improvement, which will recommend itself to thetrade;

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-- Theimproved method of uniting the tops and bottoms to the sides of squaresheet-metal cans, bystrik in g up the same in'a slightly curved form,substantially as shown infigs. 2 and 3,ffor the purpose specified.

The above specification of my invention signed by me, this l6th dayofDecember, 1868.
